The rocker arm is the part that drives the valve to open and close. In the process of opening and closing the door of the car, the rocker arm is subject to huge friction. Therefore, the production usually requires the rocker arm to have high hardness, high wear resistance, high service life and high fatigue resistance. In order to meet these working requirements of the rocker arm, many manufacturers use IGBT medium frequency induction heating power supply for quenching heat treatment.
The IGBT medium frequency induction heating power supply adds an automatic frequency sweep and repeated start function on the basis of zero voltage start, the voltage and current circuits are closely tracked, the start and stop of the equipment are smooth and stable, and there is no current impact. When it performs quenching heat treatment on the rocker arm, the quenching speed is very fast, which effectively avoids the occurrence of oxidation and decarburization, ensures the quenching quality of the rocker arm, and greatly increases the hardness of the rocker arm after quenching, which meets the requirements of the work. need.
The rocker arm adopts IGBT medium frequency induction heating power supply for quenching heat treatment, which avoids the occurrence of defects such as oxidation, decarburization, cracks, and deformation. What is even better is that the equipment will not produce noise and dust during the working process, which greatly improves the working environment of the workers and enables the workers to achieve environmentally friendly production.
